Applied Research On The Instability And Stabilization Of Dip Bedded Rock Slopes

The dip bedded rock slope is one of the familiar types of cutting slopes at present, its engineering characters take on large quantity, distribution and instability. The instability analysis and stabilized works are short of theory analysis and application study of convenience and quantity. In this paper, some difficult problems in numerical calculation, such as inhomogeneous characteristic and discontinuity on bedded rock, were solved with typical equivalent unit We obtained orthotropic mechanical parameters of bedded rock by a series of numerical tests. The dip bedded rock was endowed with orthotropic plastic material. Then we analyzed and simulated cutting process of dip bedded rock slope by finite element method, and summarized instability models of dip bedded rock slope. And so we gave the stabilized works corresponding to the instability models. Consequently, a convenient and applied technique to simulate instability and stability works was offered in this paper. It was testified that it was a feasible and applicable technique by simulated instability and stability works of a engineering case.
